Purpose: In this study a system dynamics methodology was used to identify correlation and nonlinear feedback structure among factors affecting unplanned extubation (UE) of ICU patients and to construct and verify a simulation model. Methods: Factors affecting UE were identified through a theoretical background established by reviewing literature and preceding studies and referencing various statistical data. Related variables were decided through verification of content validity by an expert group. A causal loop diagram (CLD) was made based on the variables. Stock & Flow modeling using Vensim PLE Plus Version 6.0b was performed to establish a model for UE. Results: Based on the literature review and expert verification, 18 variables associated with UE were identified and CLD was prepared. From the prepared CLD, a model was developed by converting to the Stock & Flow Diagram. Results of the simulation showed that patient stress, patient in an agitated state, restraint application, patient movability, and individual intensive nursing were variables giving the greatest effect to UE probability. To verify agreement of the UE model with real situations, simulation with 5 cases was performed. Equation check and sensitivity analysis on TIME STEP were executed to validate model integrity. Conclusion: Results show that identification of a proper model enables prediction of UE probability. This prediction allows for adjustment of related factors, and provides basic data do develop nursing interventions to decrease UE.

The necessity of professional construction management has been increased as a construction project is getting larger, more complex and specialized. Thus, the CM market has steadily expanded since 1996 in Korea. Despite the external expanding of the CM market, experts claim that domestic CM regulations and infrastructures should be revised. Therefore, this paper developed a causal map which consists of elements vitalizing CM market. Then, the simulation model using NUMBER (Normalized Unit Modeling by Elementary Relationships) to predict the size of the CM market is established. As a result, in the case of more regulation related CM, the quantity of CM projects could not reach of construction supervision until 2020. This paper can be used as a baseline providing a prospection of the change of CM market according to causal relation between the improvement as well as the base of revitalization research of CM market based on non-institutional factors change.

As the big data technologies advance, there is an increasing interest in systematic methodologies for data-based policy determination especially in the public health area. This study proposes a method to develop an issue detection model through the collaboration with domain experts in order to intelligently detect major socio-national issues on infectious diseases based on data. At first, the factors influencing the 'domestic inflow of foreign infectious diseases' are determined and variables representing the factors are set. Thereafter, by using system dynamics methods, the causal analysis is made to find causal map indicating main influential factors. In this process, an empirical modeling is conducted through collaboration between data analysts and experts in the infectious disease domain. The proposed issue detection approach based on domain knowledges will make it possible to make a decision on policies more efficiently if the detection system is capable of continuos monitoring of the related issues.

This study conducted a survey on 414 industrial organization food service workers in the Kyungnam area to find out the effect relationship of the job characteristics of organization food service workers and its effects on job commitment and job satisfaction by recognizing the need for job application through the job characteristic model, which was the beginning of the intrinsic motivation theory for the job of organization food service workers. To accomplish the purpose of this study, the method to analyze the survey was undertaken by using the SPSS 23.0 and Amos 21.0 statistic package program via a data coding process for collected data processing. We can confirm from the analysis results that there is a statistically significant causal relationship in all factors, except task identity, which is a sub factor of job characteristic. This result reaffirms the results of previous research by showing that the worker must be allowed to ensure completion of the entire job when performing the job as the job itself is not one part of the processes. Decision-making autonomy must be given in the work process when the worker performs their job in order to raise job satisfaction and furthermore to increase job commitment. The limitation of this study is that there are limits that making generalization as the study was conducted on industrial organization food service workers in the Kyungnam area as extracted samples.

The present research aimed at researching the relationships among place attachment, residential evaluations and satisfaction in a medium-sized post-communist Romanian city. Studies on post-communist cities are scarce and this research tried to fill that gap. This research is part of a government project that intended to significantly reform three medium-sized cities in the Western part of Romania and transform the urban space. Since the three of them are relatively small-sized and close spatially, the project intends to undertake massive reforms of the communications and services of the three cities. In this article, we report findings on the city of Hunedoara. A representative random sample was selected, and a total of 384 people were interviewed, with an overall reliability of the sample of 95%. The instruments used to gather the data were the Neighbourhood Perceived Environmental Quality Scale and a composite measure of place attachment was also included. The structure of each scale was checked using exploratory factor analysis. We tested alternative causal models using structural equations modelling. Our model showed a good fit to the data and explains satisfaction in the city adequately. Results show that satisfaction is directly predicted by the general evaluation of the city and by residential privacy. Residential noise and place attachment influence satisfaction indirectly. The results are discussed and some policy recommendations are formulated.
